Said 'mixingchamber is preferably closed, and-is provided at its bottom with a layer 7 ioflthe purifying material employed; which H1821 teriali, according to the process which'js'aid apparatus -;is particularly designed; i to carry out, may he serpcntine'sand, fibrousserpentine,.'ctc.,-.as specified in my said'patent.

The

agitation causes the material 7.to mix with and be elutriated by the water, which then passes from chamber 6 into the first of a series of what may be termed segreg'atin chambersll, i. e., chambers in which t e segregating action on the oil mainly takes ..place, time being afforded therein for the completion of the operation, and, to secure intimate contact between the minute oily globules and the fine elutriated particles resulting from the abrasion of the magnesian' mineral, out of the influence of currents such 'as exist in chamber 6 which I ht sweep relatively untreated water to tfie-outlet. The agitation in'each of the chambers insures that any. relatively coarse particles which may have been carried forward shall be tumbled and disintegrated, while by drawing off the effluent water at the top the passage forward of elutriates only is much facilitated. For pickingup minute oil globules it is very desirable that the mineral be in very fine fibers or particles. The water closed and under pressure, sufficient air w 630,363, dated Aug. 8,1899.

pass over through pipes -12 into chambers 11 to agitate the water in those chambersand keep the purifying material in suspension, and likewise to bring all particles of oil in the waterin'such chambers into contact with the purifying material. The level of the water in each chamber 11 can never fall be-:

lowthe'mouth of the outlet siphon of that chamber. '1' may provide a relief outlet 14, at asuitablepoint in the system, to relieve the pressure to such extent as may be desired,;'b,efore the water enters chamber 13.

' The filter within chamber 13 may be of any suitable type. I have indicated a bag filter, such as that covered by my Patent No.

the purifyingsnaterial 7 carried by the water, and the oil particles formerly in the water and whichhave collected upon the particles ofthe material 7, are held back, the Water thus purified passing out through pipe 15.

The apparatus thus described is simple, compact, and entirely practical both in large and smaH sizes, and is particularly suitable where waste steam under slight pressure is available to operate the injector 8, as for example on shlpboard. All of its parts may be completely closed so that no Water is ,lost

By this filter,

over are provided with mechanically-oper atedrim ing and mixing devices. 'Referrin rst to the form shown in Figs. 25 inc usive, 1 indicates as beforea skimming tank, 6 a mixing chamber adapted to form a reservoir to contain a considerable uantity of the purifyin material andprovir cdbwith means for grinr ing up this material and mix-- mg it with the Water, and 13 mdlcates a filtering chamber, and 17 a segregating chamber allconiprised within the main casing 16. The skimming and segregating chambers, are

placed side by side, with the filtering chamerbeneath and the mixing chamber and The segregating chamber is provided with means for stirring and agitating the water to insure uniform action of the-purifying material and to keep such material in suspension. The device for grinding up the purifying material and mixmg it with the Water, with which chamber 6 is provided as aforesaid, consists of a plural ity of grinding disks 18 mounted on a shaft 19 in the lower art ofchamber 6.

Such Water, in passing beneath the partition, becomes thoroughly mixed with the purifyim material. The water is drawn by pipe 22 from near the bottom of tank 1, the entrance to said pipe being guarded by a partition 24 extending nearly to the bottom of, tank '1 and forming substantially acontinuation of pipe 22.

The agitator 25 within chamber 17 is of.

substantially ordinary! typo, comprising a. plurality of stirrin blades mounted on a revolving, shaft am located between transverse partitions 26 in which are openings 27 tl' rough which the water flows. By means of this agitator the purifying material is kept. t

in suspension in the Water and is broug into contact with all portions of the water, being thereby given ample opportunityto collect all particles of oil in the water. The water passes from chamberl 7 to filter chamher 1 3 throughv pipe 38.

Chamber 6 holds sufficient purifying ma terial to last a considerable time Without renewal. It may be filled to the top. The
